ROMEO PITOMASSEK AND ISIDORE H. SAMPERS, OF NEW YORK, N. Y., ASSIGNORS TO THE NOISELESS OAR AND OAR WHEEL COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

" CAR-WHEEL.

SPECIFICATION forming part of Letters Patent No. 780,541, dated January 24, 1905.

Application filed December 16, 1903. Serial No. 185,361.

To all whom it may concern:

Be it known that we,l ROMEO I. ToMAssEK and IsIDoEE H. SAMrERs, citizens of the United States, and residents ofthe borough of Manhattan, in the city and State of New York,

have invented a new and useful Oar-Wheel, of which the following is a specification.

Our invention relates to a car-wheel, with the object in view of providing a wheel of thisy character with an elastic tire, and so materially reducing the noise, wear, and tear in operating the wheel.

A practical embodiment of our invention is represented in the accompanying drawings, in which- Figure -1 is a view of a portion of the wheel in side elevation, showing it in vpositionvvith respect to the rail; and Fig. 2 is a transverse section in the plane of the line AA of Fig. 1.

Our invention-is directed particularly to the construction of a wheel with an extended elastic bearing-surface for supporting heavy cars without disturbing the present arrangement of the railway-rails; and it consists in a carwheel provided with an elastic tire on the inner side of the guard-flange which is relied upon to hold the wheel on the railway-rail.

The hub ofthe wheel is denoted by 1, and the spokes which connect the hub with the rim by 2. v l

The rim is provided with a plurality of seats for the elastic tires, in the present instance two such seats, (denoted by 3 and 4, respectively.) i

Intermediate of the seats 3 and 4 the guardflange 5 projects outwardlya distance suii- Serial No. 157,814, filed May 19, 1903.

In order to increase the elastic-tire bearingsurface for sustalning unusual weight, we locate an elastic tire 10 on the seat 4 on the in rially lessened.

ner side of the guard-flange 5. This tire 10 is locked in its position by a keeper-ring 11,v provided with a* laterally-projecting skeleton flange 12, embedded in the tire 10 in the manner shown, described, and claimed in the application above referred to.

The keeper-rings 8 and 11 are locked sef curely in position with respect to the rim of the wheel by means of bolts 13 extending through the two tires and through the intermediate annular iiange 5, the said bolts being provided with nuts 14 for drawing the rings 8 and 11 toward veach other to snugly press the tires 7 and 10 against the flange 5.

In using the additional elastic tire 10 the guard-stringer'l, such as is now common upon elevated railways, may be employed as a track and to this end may be provided with a thin metal cap or plate 16 to assist the cleaning of the upper surface of the track from ice and snow and to prevent the wood of which the stringer is commonly made from being worn, split'or splintered.

Along roads where the guard-Stringer 15 is not at present located such a Stringer may be laid without interfering with the tralc on the rail 6, and when laid the cars kmay be supplied with the wheels with their extended elastic tires utilizing both the rail 6 and the guard,- stringers 16 as tracks for sustaining-the loads transmitted thereto through-the extended elastic tires.

In the above manner the undue compression of the elastic tire because of overweight may be avoided and the noise and wear and tear now incident to railway tralic' may be mate- It is obvious that `one of the elastic tires here shown-for example, the tire 7-might y be made rigid, while the other tire, 10, might be made elastic, thus having the elastic tire supplement'the action of the rigid tire or the rigid tire supplement the action of the elastic tire, if so desired.

1. A car-wheel provided with a tread on the outer side of its guard-flange and an elastic tire forming a tread on the inner side of its guard-ilange adapted to travel along the space I 5 between the rail and the Stringer and elastic tires on the car-wheel located upon opposite sides of the guard-flange and in position to cngage respectively the rail and the Stringer.

In testimony that we claim the foregoing as 2O our invention we have signed our naines, in

presence of two Witnesses, this 14th day of December, 1903.
